The whole process philosophy is especially important when managing the crushing circuit, one of the biggest energy consumers in any plant. This is where optimisation of screening comes into play. "There are two ways of looking at it: there''s screening prior to crushing, and then screening after crushing. We want to make sure that we''ve got the

Each possible mineral recovery process has a certain size range of best performance, and the final product of the crushing/grinding circuit must match the chosen process size requirements. Proper grinding is critical in order to get good metallurgical test results, as the entirety of downstream processing is dependent on optimal grinding and recovery at this stage.

3.2.1 Crushing Equipment. Primary Crushers – Jaw and Gyratory. Within the crushing circuit, a primary crusher reduces material down to a size that can be conveyed and fed to the secondary crushing circuit. The two most common primary crushers used for coarse run-of-mine material are the jaw and gyratory crushers.

The processing of lithium-containing minerals such as spodumene, in general, comprises crushing, wet grinding in a ball mill, sizing, gravity concentration, and flotation using a fatty acid (oleic acid) as the collector. The major lithium mineral in lithium ore is spodumene, which is considered insoluble in water and dilute acids.
